I-IARVESTING MACHINE WITH SCAT'IERER.

Application filed April 3, 1926, Serial No.

The object of my invention is a combined harvesting machine andscatterer in which a framework that bears the scatterer ismounted uponthe frame of the harvesting machine so as to be capable of oscillatingupwards and downwards.

In the accompanying drawing, which illus trates the invention by way ofexample, the new machine is represented in side-view and top plan viewrespectively.

On the framework :2, which is firmly con nected with the driving frameof the harvesting machine, the framework t is mounted in a way thatadmits of an upward and downward oscillation by means of studs 3, whichlie in an axis that is parallel to the wheel axis.

At the back cross-bar a", and lying obliquely to the wheel-axis of theharvesting machine and prolonged at one end sideways so as to extendbeyond the shorter longitudinal bar of the frame 4, are provided thedriving shaft 5 and the crank shaft 7, coupled with the for mer by meansof a universal joint 6. The

oblique position of the crank shaft 7 can be changed by the adjustmentof its bearings 8 and 9. On the cranks of the shaft 7 are disposedscattering forks 10, the upwardly eX- tending portions of which areprovided with several perforations 11 and are connected with theframework t bymeans of a link i2. By the adjusting of the. point atwhich the said link acts on the forks 10, the path of the curve, whichis made by the forks when the crank shaft is rotated, is changed, Thedrive of the shaft 5 is effected from the one wheel of the harvester bymeans of a sprocket-wheel '13, mounted on the inner side, a chain 14,and a sprocket-wheel 15 fixed on the shaft 5; the said wheel'15 can becoupled with the shaft 5 by means of a clutch-coupling 16. The Vframework at is supported on the side of its longer longitudinal rod byan oscillatory caster 17. The upwardly extending'end of the axis 18 ofthe caster is vertically movable in a bushing 19, carried by theframework 4 and supports acranked lever 21, which is pivoted at 19 on abracket 20, the other end of which lever is connected with acontrol-lever 3 ly means of a link 22. By properly adjusting the lever23, the framework 4 can be 99,679, and in Switzerland April 9, 1925.

moved to a more or less inclined position, whereby the forks 10- can bepositioned higher or lower as desired. The articulated connection of theforks with the machine frame has the advantage that the forks-areprotected, If, for instance due to the.

framew rk 2 there projects towards the rear under the framework t on theside of the chain gearing l3, 14L and 15, an arm. 24iwhich is connectedby means of a toggle mm 25, 26 with the shorter longitudinal rod. of thefran'iework 4. A spring 27, connected atone end to the arm 2% and at theother end to the lower toggle member 25, tends to straighten the togglejoint 25, 26. By an adjustment of the point, at which the upper togglen'ien'iher v 26 is attached to the framework at, the tension. or thesupporting effect, of-the spiral spring 27 upon the framework lcan beregulated, that is to say, it can be. adapted. to the weight of thesame, that no tendency to torsion can arise.

With harvesting machines drawn bytrac tors, the frame which bears thescattering device can be supported on both sides by means of casters.

What I claim is:

1. In combination with a harvesting machine a scatterer, comprising aframe carrving the scattering members and pivoted to said harvestingmachine frame, said frame having unequal sides, a caster supporting thelonger side of said frame, a supporting arm secured to said harvestingmachine frame, and a spring controlled toggle joint connecting saidsupportii'ig arm and the shorter side of said frame.

2. In combination with a harvesting machine a scatterer, comprising aframe pivoted to saidharvesting machine frame and supporting thescattering members and frame havingunequal sides, a caster supportingthe 5 longer side of said frame, a movable stem carrying said caster, acontrol lever for ad- JUStlHg the position of said caster by means ofsaid stem, a supporting arm secured to said harvesting machine frame,and a spring-controlled toggle-joint connecting said support- 10 ing armand the shorter side of said frame;
